vb.net - Recursive factorial output -


i'm trying write recursive function through vb console application output factorial or number between 1 , 10. system.stackoverflowexception when run it. can explain i've done wrong?

module module1 dim number byte sub main()      console.writeline("write number 1-10")     number = console.readline()      factorialcalc()  end sub function factorialcalc()      dim counter byte      dim byte     ' dim factorial integer              if number < 1 or number > 10             console.writeline("please select number 1-10")         end if      loop until number >= 1 , number <= 10      = number              factorialcalc = number * factorialcalc(number - 1)         counter = counter + 1     loop until counter = + 1      console.writeline(factorialcalc.value)     console.readline()  end function end module

a factorial program shouldn't long. need is:

module module1     dim number integer      sub main()                     console.writeline("write number 1-10")             number = console.readline()         loop until number >= 1 , number <= 10          dim result = factorialcalc()          console.writeline(result)         console.readline()     end sub      function factorialcalc(num integer) integer         return num * if(num > 2, factorialcalc(num - 1), 2)     end function end module

asynchronous - Python asyncio task got bad yield -

i confused how play around asyncio module in python 3.4. have searching api search engine, , want each search request run either parallel, or asynchronously, don't have wait 1 search finish start another. here high-level searching api build objects raw search results. search engine using kind of asyncio mechanism, won't bother that. # no asyncio module used here class search(object): ... self.s = some_search_engine() ... def searching(self, *args, **kwargs): ret = {} # raw searching according args , kwargs , build wrapped results ... return ret to try async requests, wrote following test case test how can interact stuff asyncio module. # here testing script @asyncio.coroutine def handle(f, *args, **kwargs): r = yield f(*args, **kwargs) return r s = search() loop = asyncio.get_event_loop() loop.run_until_complete(handle(s.searching, arg1, arg2, ...)) loop.close() by running pytest, return runtimeerror: task got bad yield : {results s...

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
